Drive your 95 E320 Coupe into a big tree at a high rate of speed. See if that stops your agony.

 

I think the 25-feet-from-a-door thing is a federal law (or regulation) that applies to all federally-owned buildings and those publicly-accessed buildings whose operators have funding ties to the fed, should they wish to continue their funding ties.

Any other laws/rules/regs are mandated by individual states, then by their establishments. A lot of establishments tend to emulate the federal law (or regulation) because they reason it has merit because it's the fed [enter laugh track here].
